摘要:

目的:建立快速测定香精香料复杂基体中甜蜜素添加量的方法。方法:对样品进行柱前衍生化处理,选择C18 柱和70:30(V/V)的乙腈- 水为流动相,利用二极管阵列检测器(DAD)在314nm 波长处进行检测。结果:本法可有效消除香精香料中甜蜜素检测的假阳性问题,测得的峰面积与甜蜜素质量浓度(在2.5~250mg/L 范围内)呈线性关系,相关系数为0.9992,平均回收率为94.22%~97.19%。结论:本方法简便、快速、准确且重现性好,能准确地对香精香料复杂基体中的甜蜜素进行定性和定量分析。

Abstract:

Objective: To establish a method for rapid determination of sodium cyclamate in food flavors and fragrances that are very complex substances. Methods: Samples were subjected to precolumn derivatization. The chromatographic separation was achieved on a C18 column with a mobile phase consisting of a mixture of acetonitrile and water (70:30, V/V) and the analyte was detected with a DAD detector set at 314 nm. Results: The analytical method developed was shown to result in an effective elimination of false positive detection for sodium cyclamate in food flavors and fragrances. A good linear relationship was observed between HPLC peak area and sodium cyclamate concentration in the range of 2.5 - 250 mg/L with the correlative coefficient of 0.9992, and the average recoveries were in the range of 94.22%-97.19%. Conclusion: This method is simple, rapid, accurate and repeatable, and applicable for qualification and quantification of sodium cyclamate in food flavors and fragrances.
